Subtotal colectomy versus left hemicolectomy for the elective treatment of splenic flexure colonic neoplasia.

Background: Optimal elective surgical treatment for splenic flexure neoplasm (SFN) is unclear. Subtotal colectomy (STC) and left hemicolectomy (LHC) are the two more common strategies used.

Methods: Observational multicentric study comparing postoperative morbidity, mortality and long-term survival on patients with SFN electively operated by STC versus LHC between 2003 and 2014.

Factors influencing mortality in patients undergoing surgery for acute pancreatitis: importance of peripancreatic tissue and fluid infection.

Objectives: The aims of present study were to analyze the mortality risk factors in patients who had surgery for acute pancreatitis and to assess the importance of culturing peripancreatic tissue or fluid infection to ascertain the infection status.

Methods: Surgery was indicated both in patients with infected severe acute pancreatitis and in those with sterile pancreatitis with an unfavorable course. During surgery, cultures were taken of tissues (pancreatic necrosis and peripancreatic fat), intra-abdominal fluid, and bile.

Recurrence and virulence of colonic diverticulitis in immunocompromised patients.

Background: To evaluate the probability of recurrence and the virulence of colonic diverticulitis correlated with immunocompromised status.

Methods: Nine hundred thirty-one patients admitted in a single tertiary referral university hospital over a 14-year period were included. Patients were divided into 2 groups: group 1, 166 immunosuppressed patients, and group 2, 765 nonimmunosuppressed patients.
